Sum's place is gold! Many options of authentic Thai food is available right outside the doorstep, we didn't even get to use the kitchen to cook our food in our two-week stay. Walking distance to everything — SRT and BTS skytrain station, night market, mall, temples and the tallest statue of Buddha in Bangkok as of the current writing. It is in the residential part of Bangkok so if you're up for the experience of living like a local, away from the mostly tourist-catered downtown, this place is for you.
We didn't get to meet the host, Sum, but he's approachable and it was easy to communicate with him. WiFi is shared with the laundromat downstairs but still manageable for guests who are considering working from home. Other details in the house like the clothes steamer for creased and wrinkled outfits is a plus. Interior is done nicely too. Staying here is highly recommended!
